Cognition moves the Dioxus team onto Devin's virtual machines and testing systems

Dioxus engineers already had code running inside Devin's command line, and they arrive with a cloud harness that snapshots and forks virtual machines on five operating systems. Neither side called it an acquisition.

Warp replays your stored agent runs to decide which model gets the next ticket

The replay only works on runs Warp's infrastructure already recorded, and correctness is graded by a judge model against a rubric you write. Warp's own 30-task bake-off cost $2,130.57. It finished in under four hours.

A Berkeley scanning agent scores 100% on five AI agent benchmarks without solving a task

Berkeley's RDI center attacked the step where each benchmark computes its score, and without solving a task its own scorecard reports 100% on five of the eight, about 98% on GAIA and 73% on OSWorld.

Swapping the harness under a fixed model kept pass rate within 8 points on 50 Terminal-Bench Pro tasks

A 300-trial study swapped Goose, OpenCode and OpenHands-SDK under Qwen 3.6 Plus and MiniMax M2.5, and reports that the scaffold sets tokens per solved task and the failure mode while the score barely moves.

Databricks finds the harness swings coding-agent cost more than the model does

The company benchmarked coding agents on real tasks against its own multi-million line codebase and found that per-token price predicted almost nothing about what a finished task cost. GLM 5.2 came in at $1.28.

JetBrains' Kotlin leaderboard prices the same 86 solved tasks at 3.7x apart

DeepSeek's V4 preview cuts million-token KV cache to a tenth of V3.2's

The efficiency claims are self-reported and measured against DeepSeek's own prior model, but the weights are MIT-licensed and already pulled 1.78 million times, which is what turns a ratio into a number a buyer can carry into a renewal.

Measuring each patch against the human fix on the same bug leaves 13 of 14 models messier

The study counts only complexity and dead code, because those are the two pyscn metrics that stay exact when you analyze just the files a patch touched. The human's own commit trips the same rule 24% of the time.

SWE-Gate flunks 221 of 644 test-passing agent patches on rules mined from PR comments

SWE-Gate scores agent patches at two gates instead of one. The third that clear tests but fail mined review rules are measured against a pipeline that runs tests and nothing else, while most teams run a pipeline with additional checks beyond that.

A $28 agent run swapped BCD for base-2^64 limbs and built its own oracle

A dev.to writeup attributes 612.9M tokens and $28.35 to four days of DeepSeek Harness work on a C# arbitrary-precision library, and the part worth reading is how the agent checked its own rewrite.

IFM ships K2 Horizon's checkpoints and training logs for outsiders to audit

Six models from 0.9B to 375B, four of them pretrained on one shared token sequence, mean IFM's sparse-versus-dense efficiency claim can be tested by outsiders at a scale they can actually afford to re-run.

Ten planted bugs, about a dollar of API spend, and the case for grading the log not the answer

A dev.to writeup grades a bug-fixing agent on its tool calls rather than its patch. Thirty documented runs cost roughly a dollar; the expensive input is the hand-built dataset behind them.

SWE-Bench does not measure the job: why agent scores are the wrong readiness signal

A practitioner's field notes put curated agent evaluations on one axis and production intent resolution on another. The cost of confusing them gets billed per session, not per query.

The refusal came back labelled "infeasible": reading a planner/critic jailbreak test

A 170-goal agent field test costs $0.49. Proving it actually passed costs more.

PlannerCritic's sweeps are cheap enough to gate every release. The harder problem is telling a clean run from a rig that quietly counted nothing.

Harness-Bench makes the scaffold a measured variable, and model-only scores lose meaning

AI code has sat at 55% secure for two years. Waiting for a better model is not a plan.

Veracode ran more than 150 models over 80 tasks and found 45% of the output carries a known weakness. The level is bad; the flat two-year trend is the part that changes your plan.
